To all whom it may concern:

Beit known that I, JOHN S. KIDD, a citizen of the United States of America, and aresident of Des Moines,in the county of Polk and State of Iowa, have invented an Improved W'agon Dump and Elevator, of which the following isa specification.

My object is' to reduce the height of the platform upon which a wagon is drawn by horses hitched to the wagon, as required, to favor the horses, and also to utilize the weight of the suspended elevator-box for raising the front end of a wagon preparatory to dumping its contents into the elevator-box.

My invention consists in the construction and combination of an adjustable section of a platform with a iixed section and an elevatorframe in such a manner that the adjustable section can be placed in an inclined position, while a loaded wagon is upon it, and then moved longitudinally toward the elevator-box into which the contents of the wagon are to be dumped, and also in combining the elevator-box with the platform and the elevatorframe and hoisting mechanism in such a manner that the weight of the elevator-box can be applied to the rear end of the adjustable view of a section of the frame that has bear-- ings xed thereto to'engage the end of crossbars fixed to the bottom of the box.

A represents the fixed portion ofthe wagonplatform, and A2 the elevator-frame to which it is attached.

B is the frame of the adjustable section of the wagon-platform, preferably supported at its front end upon wheels B2, that are connected therewith by means of bearers B2, fixed to side bars of the frame.

C represents short rails or tracks fixed to the frame of the fixed portion of theplatform in such a manner that the wheels B2 will travel thereon.

D are straight bars pivoted to the rear endsl of the side bars -of the frame B, and also to the side bars at the base of the fixed portion A of the complete platform, in such a manner that they will swing vertically to aid in lifting the rear end of the adjustable section and support it in an inclined position, as indicated by dotted lines in Fig. 1.

F is a shaft adapted to rotate in bearings xed to the platform-frame A'.

F is a tubular shaft or sleeve on the shaft F.

F2 are drums fixed on the ends of the shaft F, and F3 drums on the ends of the sleeve.

F4 is a clutch for connecting the sleeve with theshaft F so they will rotate jointly.

G is a rotating shaft in parallel position with the shaft F. It has a fixed drum G2 at one end, to which a rope Gr3 is fixed for operating the shaft.

II is a gear-wheel fixed to the other end of the shaft G to engage a wheel H2, fixed to the shaft F in such a manner that motion and power will be transmitted from one shaft to the other in raising and lowering the adjustable section B of the platform and an lelevatorbox.

J are ropes fixed to the rear and top corners of the section B of the platform and extended over directing-pulleys J2, attached to the elevator-frame, and from thence down to the drums F3, to which they are attached.

K is a frame suspended fromthe top of the elevator-frame by means of ropes K2, that pass over directing-pulleys in a common way and are fastened to the drums F2.

L are metal castings fixed to the frame, to serve as corner-braces in the frame and also as bearings or fulcrums upon which to support and operate an elevator-box M, that has two bars N fixed across its bottom. The bars have journals N2 on their ends, that fit and operate on the fulcrums L in such a manner that the box can be tilted in reverse ways at the will of the operator, as required to discharge the contents of the box in different directions at different times.

P is a ratchet-wheel on the end of the shaft G, and P2 is a pawl pivoted to the platformframe A in such a manner that any backlash of the hoisting-rope G3 will be prevented as the loaded box M is elevated, and also as required to retain the box elevated.V

To place a loaded wagon upon the adjustable section B of the platform, an inclined approach is placed at the front end of said section, as indicated by dotted lines in Fig. l, and the wagon then advanced over the approach to the top of the platform, by means of horses and by driving through under the elevator-box M, suspended over the approach. The approach is then removed and the pawl P2 adjusted to allow the shafts G and F torotate and the box M to descend and rest upon the ground at the rear end of the platform-section B. As thebox descends by force of gravity, the ropes K2 unwind from the drulns F2, and in so doing rotate the shaft F and wind the ropes J on the drums F3, as required to lift the rear end of the platformsection B and the front end of the wagon thereon. As the box descends and the wagon and adjustable section are brought into an inclined position', they are also jointly advanced toward the elevator-box, as required to bring the end of the wagon-box in proper position to discharge its contents into the elevator-box. As the box descends, the horses are backed and aid in tilting the dump-section and wagon. \Vhen the wagon is unloaded, the sleeve is freed from the shaft F by means of the clutch F4, to allow the sleeve and drums on its ends to rotate and unwind the ropes J from the drums F3, as required to allow the elevated platform-section B to return to its normal level position, so that the wagon can be advanced and the hoisting-rope G3 attached to the wagon and the loaded elevator-box hoisted as the wagon is moved from the platform.

By doubling the ropes J over the pulleys J2 and connecting them with the drums F3 and the movable end of the platform, and connecting the ropes K2 with the drums F2, of larger diameter, on the sleeve F, to which the drums F3 are fixed, the power of gravity inherent in the box is augmented sufficiently to operate the platform-section in the manner described.

In my former application, hereinbefore referred to, I raise and lower an elevator-box by means of ropes passed over pulleys in the same manner as now shown; but the ropes are' not connected with the dumping-platform for the purpose of utilizing the weight of the box to lift the platform and dumping the wagon.

I am aware elevator-boxes have been suspended from the top of the frame and connected with mechanism on the platform and base of iheframe by means of ropes for the purpose of raising and lowering the box; but my combination of an elevator-box with a wagon-dumping platform and operating mechanism in such a manncrthat the weight of the box can be utilized to lift and dump a wagon is novel and greatly advantageous.

I claim as my inventionl. In a wagon dump and elevator, the combination of a platform-section that is supported upon traction-wheels at one end and hinged to a fixed platform at its other end by means of straight bars in such a manner that when the hinged end is elevated the complete section will be moved longitudinally toward an elevator-box, for the purposes stated.

2. The platform -section B, having fixed bearings B2 and wheels B3 at its `front end and pivoted bars D at its rear end,in combination with a platform and elevatorframe and mechanism for lifting the rear end of the movable platform section, for the purposes stated.

3. The ropes J, passed over pulleys J 2, attached to an elevatorframe,the rotating sleeve or shaft F', having fixed drums F3, and the platform-section B, supported upon wheels at its front end and connected at its rear end with the fixed platform by means of bars D, arranged and combined to operate in the manner set forth.

4. The combination of the shaft G, having a fixed drum G2, and fixed gear-wheel Il, the shaft F, having fixed drums F2, the sleeve F, having iixed drums F3, the ropes J, extended over pulleys J2, attached to the elevatorframe, the platform-section B, mounted on wheels at its front end and connected with the fixed platform by means of bars D, and an elevator-box suspended from the top of the elevator-frame by means of ropes fixed to the drums F2, to operate in the manner set forth, for the purposes stated.

5. A wagon dump and elevator comprising an elevator-f rame an d a wagon-platform fixed to the base of the elevator-frame, an adjustable platform-section supported upon traction-wheels at its front end, hinged to the fixed platform at its rear ends by means of bars that allow vertical adjustment and longitudinal motion to the adjustable section, an elevator-box suspended from the top of the elevator-frame by means of ropes and pulleys, a rotating shafthaving fixed drums to which said ropes are attached to raise and lower the said box, mechanism for rotating` shaft, and ropes extended over pulleys attached to the elevator-frame and connected with the shaft and also with the rear end of the adjustable platform sect-ion, arranged and combined to operate in the manner set forth, for the purposes stated.

G. In a wagon dump and elevator, the combination of a suspended elevator-box and adjustable platform-section and mechanism for IOO transferring the Weight of the box to the said and connected with the rope-operating meehplatfor1nseetion,-forthe purpose of elevating anism for the purpose of dumping the oonro one ed of a agon on the platform-section. tents of the wagon into the elevator-box.
